A carbon fiber tow sizing treatment device

Abstract

This utility model relates to the field of carbon fiber tow sizing technology and discloses a carbon fiber tow sizing treatment device, including an impregnation tank. A displacement module is located at the center of the left and right sides of the outer end of the impregnation tank. An adjustment module is located at the center of the front end of the displacement module. A support module is located on the inner side of the upper end of the displacement module, and a pressing module is located on the inner side of the upper end of the support module. This utility model uses the pressing module, positioned in the center above the impregnation tank. Two impregnation rollers, in conjunction with three feed rollers horizontally distributed inside the impregnation tank, lower the pressing module via a lifting motor during sizing. This causes the tow passing through the feed rollers and impregnation rollers to form a W-shaped impregnation path inside the impregnation tank, changing the traditional single impregnation to multiple impregnations. This significantly extends the contact time between the tow and the sizing solution, allowing the sizing solution to fully penetrate the tow and improving the uniformity of sizing.

Description

Technical Field

[0001] This utility model relates to the field of carbon fiber tow sizing technology, specifically a carbon fiber tow sizing treatment device. Background Technology

[0002] Carbon fiber tow is a bundle of carbon fiber semi-finished products formed by processes such as bundling, sizing, and winding, consisting of dozens to tens of thousands of carbon fiber monofilaments with a diameter of 5–7 μm. It is the core raw material for carbon fiber product processing.

[0003] Currently, carbon fiber tow requires a sizing treatment device during sizing. While existing carbon fiber tow sizing treatment devices, such as the one disclosed in Chinese Utility Model Patent Publication No. CN222205728U, effectively adjust the height of the impregnation roller, facilitating the threading of the carbon fiber tow and possessing high practical value, in actual sizing, this device can only form a V-shaped impregnation path in the impregnation tank. This results in a short contact time between the carbon fiber tow and the sizing liquid, insufficient impregnation time, and a tendency for uneven sizing. Furthermore, the single impregnation mechanism's ability to adjust the wrap angle and tension dimension of the carbon fiber tow in the sizing liquid is too small for different specifications of carbon fiber tow, indicating insufficient adaptability. Therefore, this utility model aims to solve the aforementioned problems by providing a carbon fiber tow sizing treatment device. Utility Model Content

At the same time, when the single impregnation mechanism is used to sizing carbon fiber tows of different specifications, it can change the wrap angle and tension dimension of the carbon fiber tow in the slurry, which is too small and has insufficient adaptability.

The adjustment motor is located at the front end of the external threaded screw, and the outer bearing is sleeved on the rear end of the external threaded screw.

[0008] Optionally, the support module includes a rear column, a front column, an insert block, a wire hole, a socket, and a lifting groove.

The upper ends of the rear column and the front column have sockets inside. The rear column and the front column have symmetrical lifting grooves on opposite sides.

[0009] Optionally, the pressing module includes a longitudinal rear rod, a longitudinal front rod, a support rod, a pressing rod, a stabilizing rod, a vertical plate, and a reinforcing bolt. The longitudinal rear rod is provided with a longitudinal front rod on its front side. The lower ends of the longitudinal rear rod and the longitudinal front rod on opposite sides are provided with a support rod. The upper ends of the longitudinal rear rod and the longitudinal front rod are provided with a pressing rod. The lower end of the pressing rod is provided with a stabilizing rod. The left and right ends of the stabilizing rod are provided with vertical plates. The contact ends of the longitudinal rear rod and the longitudinal front rod with the support rod are provided with reinforcing bolts.

[0010] Optionally, the flow guiding module includes a flow guiding frame, a base frame, a guide rod, a reinforcing plate, a blow rod sleeve, and a stop rod. The base frame is provided on the rear side of the lower end of the flow guiding frame, the guide rod is provided on the front and rear sides of the inner side of the upper end of the flow guiding frame, the reinforcing plate is provided on the left and right sides of the front end of the flow guiding frame, the blow rod sleeve is provided in the middle of the upper inclined end of the flow guiding frame, and the stop rod is provided on the left and right sides of the front end of the base frame.

[0011] Optionally, the tightening module includes a T-block, a tightening block, and a tightening bolt.

[0012] Optionally, the displacement module, adjustment module, and support module are symmetrically distributed in two sets. The rear end of the adjustment module passes through the interior of the displacement module and extends to the outside. The lower end of the pressing module extends into the interior of the support module. The transmission end of the lifting motor and the contact end of the pressing module are assembled through an internal threaded slider. Two impregnation rollers are symmetrically distributed in front and behind.

[0013] In summary, the technical effects and advantages of this utility model are as follows: 1. This utility model has a reasonable structure. The pressing module is arranged in the middle of the upper part of the sizing tank. Then, two sizing rollers are installed in the middle of the lower end of the pressing module. Together with three feed rollers installed horizontally inside the sizing tank, when the yarn bundle is sized, the pressing module is driven to descend as a whole by the lifting motor. This allows the yarn bundle passing through the feed rollers and sizing rollers to form a W-shaped sizing path inside the sizing tank. This changes the traditional single sizing to multiple sizing, which can significantly prolong the contact time between the yarn bundle and the sizing liquid. This is conducive to the sizing liquid fully wetting the inside of the yarn bundle and improving the uniformity of sizing.

[0014] 2. In this utility model, the support module is installed on the inner side of the upper end by a displacement module. When it is necessary to adjust the wrap angle and tension of the filament in the slurry, the positioning pin of the fixed internal thread slider is removed first. Then the adjustment module starts to work, driving the support module to move back and forth along the displacement groove at the upper end of the displacement module. Then the pressure module installed on the inner side of the upper end of the support module also moves synchronously. With the filament feed roller installed in a fixed position, the filament dip roller moves with the pressure module, changing the wrap angle and tension of the filament in the slurry, so as to adapt to the slurry work of filaments of different specifications and improve the overall adaptability of the device.

The reinforcing bolt 507 is provided at the contact end between the longitudinal rear rod 501 and the longitudinal front rod 502 and the support rod 503.

[0019] The impregnation tank 1 is an integral structure. The displacement module 2 is reinforced to the impregnation tank 1 by welding. The contact end between the adjustment module 3 and the displacement module 2 is reinforced by bolts. The contact end between the support module 4 and the impregnation tank 1 is provided with a protrusion. The contact end of the protrusion between the impregnation tank 1 and the support module 4 is provided with a transverse groove. The displacement module 2, adjustment module 3 and support module 4 are symmetrically distributed in two sets. The rear end of the adjustment module 3 penetrates the interior of the displacement module 2 and continues to extend to the outside. The lower end of the pressing module 5 extends into the interior of the support module 4. The transmission end of the lifting motor 6 and the contact end of the pressing module 5 are assembled through the internal threaded slider 12. The contact end between the feed roller 7 and the impregnation tank 1 is reinforced with bolts, and the contact end between the flow guiding module 8 and the impregnation tank 1 is also reinforced with bolts. The feed pipe 9 and the discharge pipe 10 are of equal size and shape, and their rear ends penetrate the outer wall of the front end of the impregnation tank 1 and extend to the rear interior of the impregnation tank 1. The feed pipe 9 and the discharge pipe 10 can be connected to an external circulation pump through pipelines, so that the external circulation pump can carry the slurry and the impregnation tank 1 itself to form a circulation conveying structure, reducing the sedimentation of the slurry inside the impregnation tank 1. The external circulation pump connecting the feed pipe 9 and the discharge pipe 10 is a known existing technology and can be used as needed. The tightening module 11 extends into the interior of the displacement module 2, and the tightening modules 11 are symmetrically distributed on the front and rear sides of the rear column 401 and the front column 402, fitting together. The contact end of the internal thread slider 12 with the support rod 503 has a slot, and a positioning hole is provided on the outer side of the slot. A positioning pin is installed between the internal thread slider 12 and the positioning hole. Two filament-impregnating rollers 13 are symmetrically distributed front and rear. The contact ends of the filament-impregnating rollers 13 and the pressing module 5 are interlocked, and the contact ends of both are also limited. The longitudinal rear rod 501 and the longitudinal front rod 502 are equal in size and shape. Meanwhile, the longitudinal...

The support rod 503 has a transverse groove in the middle, which is compatible with the internal thread slider 12. The transverse groove has positioning holes on both sides. The support rod 503 is fixed to the longitudinal rear rod 501 and longitudinal front rod 502 by the reinforcing bolt 507. The contact end of the stabilizer rod 505 and the vertical plate 506 is threaded, and the contact end of the two is limited and tightened.

[0020] The pressing module 5 is positioned in the middle of the upper part of the sizing tank 1. Two sizing rollers 13 are then installed in the middle of the lower end of the pressing module 5. Together with three feed rollers 7 installed horizontally inside the sizing tank 1, when the yarn is sized, the pressing module 5 is driven to descend as a whole by the lifting motor 6. This allows the yarn that passes through the feed rollers 7 and the sizing rollers 13 to form a W-shaped sizing path inside the sizing tank 1. This changes the traditional single sizing to multiple sizing, which can significantly extend the contact time between the yarn and the sizing liquid, and facilitates the full penetration of the sizing liquid into the yarn, thereby improving the uniformity of sizing.

[0021] As an optional implementation method in this embodiment, such as Figures 1 to 4 As shown, displacement module 2 includes a right displacement rail 201, a left displacement rail 202, a displacement groove 203, and a central screw hole 204. The left displacement rail 202 is located on the left side of the right displacement rail 201. Displacement grooves 203 are provided on the inner sides of the upper ends of both the right and left displacement rails 201 and 202, and these grooves are symmetrically distributed front and back. A central screw hole 204 is provided in the middle of the upper ends of both the right and left displacement rails 201 and 202. Adjustment module 3 includes a central rod 301, an external threaded screw 302, an inner bearing 303, an adjustment motor 304, and an outer bearing 305. External threaded screws 302 are provided on both the front and rear sides of the outer end of the central rod 301. The central rod 301 and the external threaded screw 302 are integrally formed. Inner bearings 303 are sleeved and installed on both the front and rear sides of the outer end of the central rod 301. Two inner bearings 303 are symmetrically distributed front and back. An adjustment motor 304 is located at the front end of the external threaded screw 302. An outer bearing 305 is sleeved and installed at the rear end of the threaded rod 302; the support module 4 includes a rear column 401, a front column 402, an inner block 403, a thread hole 404, an insertion hole 405, and a lifting groove 406. The front column 402 is provided on the front side of the rear column 401. The lower ends of both the rear column 401 and the front column 402 are provided with inner blocks 403. The inner blocks 403 have thread holes 404 inside. The upper ends of both the rear column 401 and the front column 402 have insertion holes 405 inside. Hole 405, lifting grooves 406 are symmetrically provided on opposite sides of the rear pillar 401 and the front pillar 402; the tightening module 11 includes a T-shaped block 111, a tightening block 112 and a tightening bolt 113. The tightening block 112 is provided below the T-shaped block 111. The tightening bolt 113 is threadedly installed on the upper end of the T-shaped block 111. The lower end thread of the tightening bolt 113 passes through the interior of the T-shaped block 111 and continues to extend downwards to the interior of the upper end of the tightening block 112.

[0022] The right displacement rail 201 and the left displacement rail 202 are exactly the same in size and shape. The displacement groove 203 consists of two sections, front and rear, and the size and length of the two end displacement grooves 203 are equal. The central screw hole 204 is compatible with the bolts fixing the lifting motor 6. The middle rod 301 and the external threaded screw 302 are integrally structured. There are two external threaded screws 302 symmetrically distributed front and rear. The external thread angles of the two external threaded screws 302 are exactly opposite, which are compatible with the rear column 401 and the lower part of the front column 402. The inner side of the end insert block 403 has a threaded hole 404. Two inner bearings 303 are symmetrically distributed front and rear. The transmission end of the adjusting motor 304 is integrally formed with the front external threaded screw 302. The outer bearing 305 is sleeved and installed on the rear side of the outer end of the rear external threaded screw 302. Simultaneously, the outer bearing 305 is embedded and installed on the inner side of the rear end of the right displacement rail 201 and the left displacement rail 202. Two rear columns 401 and two front columns 402 are symmetrically distributed left and right. The upper end of the front pillar 402 on the same side is provided with a protrusion. The embedded block 403 is integrally formed with the rear pillar 401 and the front pillar 402. The threaded hole 404 is adapted to the external threaded screw 302. The insertion hole 405 is interconnected with the lifting groove 406. The shape of the groove formed by the combination of the two is adapted to the shape formed by the contact end of the longitudinal rear rod 501, the longitudinal front rod 502 and the support rod 503. The outer diameter of the lower end of the T-block 111 is adapted to the inner diameter of the upper end of the groove of the displacement groove 203. The outer diameter of the tightening block 112 is compatible with the inner diameter of the lower slot of the displacement groove 203. The tightening bolt 113 passes through the interior of the T-shaped block 111 and extends to the interior of the lower tightening block 112. The T-shaped block 111 and the tightening block 112 can be tightened by the tightening bolt 113, so that they are fixed in the displacement groove 203 and fit against the front and rear sides of the rear pillar 401 and the front pillar 402 from both front and rear directions, thereby playing a role in limiting and fixing the rear pillar 401 and the front pillar 402.

[0023] By using the displacement module 2, the support module 4 is installed on the inner side of the upper end. When it is necessary to adjust the wrap angle and tension of the filament in the slurry, the positioning pin of the fixed internal thread slider 12 is removed first. Then the adjustment module 3 starts to work, driving the support module 4 to move back and forth along the displacement groove 203 at the upper end of the displacement module 2. This causes the pressure module 5 installed on the inner side of the upper end of the support module 4 to move synchronously. With the infeed roller 7 still in the installation position, the immersion roller 13 moves with the pressure module 5, changing the wrap angle and tension of the filament in the slurry, so as to adapt to the slurry work of filaments of different specifications and improve the overall adaptability of the device.

[0024] like Figure 1 and Figure 8As shown, in this embodiment, the flow guiding module 8 includes a flow guiding frame 801, a base frame 802, a guide rod 803, a reinforcing plate 804, a blow rod sleeve 805, and a stop rod 806. The base frame 802 is provided on the rear side of the lower end of the flow guiding frame 801. The guide rod 803 is provided on the front and rear sides of the inner side of the upper end of the flow guiding frame 801. The reinforcing plate 804 is provided on the left and right sides of the front end of the flow guiding frame 801. The blow rod sleeve 805 is provided in the middle of the inclined end above the flow guiding frame 801. The stop rod 806 is provided on the left and right sides of the front end of the base frame 802.

[0025] The flow guide frame 801 is reinforced with bolts to the base frame 802. The guide rod 803 is sleeved and installed inside the flow guide frame 801. Two reinforcing plates 804 are symmetrically distributed on the left and right sides. The two reinforcing plates 804 and the flow guide frame 801 are integrated into one structure. The blow rod sleeve 805 is welded and fixed to the flow guide frame 801 to form an integrated structure. The push rod 806 and the base frame 802 are integrated into one structure. The front end of the push rod 806 is reinforced with bolts to the contact end with the slurry tank 1.

[0026] The base frame 802 provides support at the lower end of the guide frame 801, and together with the abutment rod 806, it is reinforced with the impregnation tank 1 to ensure the stability of the guide frame 801 during operation. At the same time, through the design of the blow rod sleeve 805, the blow rod with the required power can be selected according to the production specifications and installed inside the blow rod sleeve 805. Subsequent replacement can be done by simply disassembling, saving time and effort.

[0027] The working principle of this practical application is as follows: The pressing module 5 is positioned in the middle of the upper part of the sizing tank 1. Two sizing rollers 13 are then installed in the middle of the lower end of the pressing module 5, in conjunction with three feed rollers 7 horizontally distributed inside the sizing tank 1. When the yarn is sized, the pressing module 5 is lowered by the lifting motor 6, allowing the yarn passing through the feed rollers 7 and sizing rollers 13 to form a W-shaped sizing path inside the sizing tank 1. This changes the traditional single sizing to multiple sizing, significantly extending the contact time between the yarn and the sizing solution, facilitating thorough sizing penetration, and improving sizing uniformity. Secondly, through the set displacement... Module 2, with support module 4 installed on the upper inner side, when it is necessary to adjust the wrap angle and tension of the filament in the slurry, first remove the positioning pin of the fixed internal thread slider 12, and then adjust module 3 starts to work, driving support module 4 to move back and forth along the displacement groove 203 at the upper end of displacement module 2, and then driving the pressing module 5 installed on the upper inner side of support module 4 to move synchronously. With the filament feed roller 7 installed in a fixed position, the filament dip roller 13 moves with the pressing module 5, changing the wrap angle and tension of the filament in the slurry, so as to adapt to the slurry work of filaments of different specifications and improve the overall adaptability of the device.

[0028] The electrical components mentioned in this article are all connected to an external controller and mains power, and the controller can be a conventional known device such as a computer that provides control.
